DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The embodiments set forth below represent the necessary information to enable those skilled in the art to practice the invention and illustrate the best mode of practicing the invention. Upon reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the invention and will recognize applications of these concepts not particularly addressed herein. It should be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims.

FIG. 1 is a flow chart illustrating a process for obtaining and presenting information to a user playing a media item identifying playback positions of a number of other users also playing the media item according to one embodiment of the present invention. Note that while much of the discussion herein focuses on playback of video items, the present invention is equally applicable to other types of media items such as, for example, audio items (e.g., songs, audio books, radio broadcasts, podcasts, or the like). First, a user begins playback of a video item (step100). As discussed below, the video item may be a video item stored locally at a device of the user providing playback of the video item, downloaded from a source such as a content server, streamed from a source such as a content server, or the like.

More specifically, in order to perform filtering, a list of other users currently playing video item may first be obtained. The list of other users may then be filtered based on one or more criteria such as, for example, geographic location, geographic distance from the user, demographic information (e.g., age, sex, or the like), a social network of the user, similarity of the user profiles and/or preferences of the other user with that of the user, or the like. For example, the list of other users currently playing the video item may be filtered based on geographic location to remove those other users that are not located within the same geographic location as the user. The geographic location may be any geographic region such as, but not limited to, a country, a region of a country, a state, a city, a town, an area defined by a telephone area code, an area defined by a zip code, an area defined by geographic designations such as latitude and longitude, or the like. As another example, the list of other users may be filtered to remove those other users that are not within a defined geographic, or physical, distance from the user. As another example, the list of other users may be filtered based on demographic information to remove those other users that do not have demographics matching those of the user, demographics identified by the user as preferred demographics, demographics within a defined range of the demographics of the user, or the like. As a final example, the list of other users may be filtered to remove those other users that are not within a social network of the user, within a defined logical distance from the user in a social network of the user, on a contact list such as an email contact list or buddy list of the user, or the like.

At this point, the playback information identifying the playback positions of the other users is presented to the user during playback of the media item (step104). Again, the other users for which the playback information is presented may be all other users currently viewing the video item. Alternatively, filtering may be performed at the user device based on one or more of the criteria discussed above such that playback information for only a subset of all of the users currently viewing the video item is presented to the user.

The playback information identifying the playback positions of the other users may be presented, for example, on a scrubber bar, as a list of names or other identifiers of the other users viewing the video item and their playback positions, or the like. Note, however, that the particular manner in which the playback information is presented may vary depending on the particular embodiment. For example, if the device is a personal computer, the playback information may be presented in a scrubber bar provided by a media player application, a scrubber bar provided by a plug-in to the media player application, a separate window provided by a plug-in to the media player application, or the like. As another example, if playback of the video item is provided via a web browser, the playback information may be presented via the same window or a separate window provided by the web browser. As final example, if the device is a set-top box, the playback information may be presented as an overlay that graphically indicates the playback positions of the other users, provides a list of the other users and their playback positions, or the like.

Note that additional information regarding the other users may also be presented. For example, in addition to the playback information, for each of the other users, a status of the other user, contextual information regarding the other user, personal information (e.g., name, telephone number, email address, geographic location, etc.), or the like may be presented or available for presentation upon request. The status of a user may be, for example, information indicating that the user is or is not available for a chat session, information identifying a device on which the other user is viewing the video item, or the like. The contextual information may include, for example, information defining and/or identifying a number of users that are currently following the other user in playback, information identifying another user that the other user is following, information regarding what portion of the video item the other user is watching, or the like. The information regarding the portion of the video item that the other user is watching may be, for example, a screen shot, a video clip, or the like. Also, if the users for which the playback information is presented were selected from all other users viewing the video item via a filtering process, then the contextual information may also include information regarding why the other user was selected. For example, if filtering is performed based on geographic location, the contextual information may include the geographic location of the other user, distance between the other user and the user to which the contextual information is presented, or the like. Also note that the user to which the playback information is presented may choose to no longer display the playback information if desired. Similarly, the other users may be enabled to choose to stop sharing their playback information at any time.

In one embodiment, the user may be enabled to configure how the playback information is presented. More specifically, the user may, for example, define a maximum number of other users for which to present playback information, define one or more criteria for selecting the other users for which to present playback information from a larger number of other users viewing the video item, choose to have the information identifying the other users presented but not their playback locations, or the like. In addition or alternatively, the other users may be enabled to configure privacy settings that define the types of information to be shared with the specific user viewing the video item or any other user viewing the video item. For example, a user may define his privacy settings such that his shared playback information includes information identifying the video item that he is viewing but not his specific playback position. The privacy settings may additionally or alternatively define the types of additional information to be shared with the specific user viewing the video item or any other user viewing the video item. For example, the user may define his privacy settings such that the contextual information for the user is not shared with other users viewing the video item.

Thereafter, the playback information identifying the playback positions of the other users presented to the user is updated (step106). The playback information is first updated to reflect changes in the playback positions of the other users due to continued playback of the video item by the other users. So, for example, if the playback information initially indicated that user A's playback position is at the twelve-minute and thirty-second (00:12:30) mark, then continued playback by user A is assumed such that the playback position of user A is updated periodically to reflect the updated playback position of user A. Thus, after one-minute, the playback position of user A would be the thirteen-minute and thirty-second (00:13:30) mark. In addition, the playback information is updated to reflect playback control events such as pausing, rewinding, fast-forwarding, or the like by the other users during playback of the video item. Thus, using the example given above, if user A fast-forwards to the fifteen-minute and twenty-second (00:15:20) mark, then the playback information presented to the user is updated to reflect user A's new playback position.

In this example, at some point during playback, user input is received from the user identifying a desired action to take with respect to one or more of the other users currently playing the video item (step108). For example, the user may be enabled to select one of the other users and choose to “follow” that user during playback of the video item, select one of the other users and choose to “follow” that user during playback of the video item and any subsequently played video items (e.g., “follow” that user during playback of any number of video items in a playback session), select one or more of the other users and choose to have the selected users “follow” him during playback of the video item, select one of the other users and choose to have the selected users “follow” him during playback of the video item and any subsequently played video items (e.g., “follow” him during playback of any number of video items in a playback session), or the like. As another example, the user may be enabled to select one or more of the other users and choose to initiate a chat session or instant messaging session with the selected users, or the like. As a final example, the user may be enabled to enter a comment where the comment is then automatically provided to other users in close proximity to the user in playback of the video item. For instance, the message may automatically be provided to other users within five (5) minutes of the user's playback position.

In response, the desired action is effected (step110). For example, if the user selects one of the other users and chooses to follow that user during playback of the video item, then playback of the video item to the user is controlled such that it is substantially synchronized to playback by the selected user. Note that playback of the video item to the user may be synchronized to playback by the selected user by controlling playback based on the playback information for the selected user. If the user selects one or more of the other users and chooses to have the selected users follow him during playback of the video item, the user device may send a corresponding request or some central service, such as the playback information broker, may send a corresponding request to user devices of the selected users. The selected users may then be forced for follow the user during playback. Alternatively, the selected users may then be enabled to choose whether to follow the user during playback of the video item. As a final example, if the user chooses to initiate a chat session, a chat session with the one or more selected other users may be initiated with the one or more selected users via an associated chat application.

FIG. 2 illustrates an exemplary graphical user interface (GUI)10 for presenting, to a user playing a video item, playback information identifying playback positions of other users also playing the video item at that time according to one embodiment of the present invention. While theGUI10 of this example is one that would typically be provided by a software application running on a personal computer, the present invention is not limited thereto. A similar interface may be provided in a web browser if the user is playing the video item via the web browser. Still further, a similar interface may be provided on other types of devices such as, for example, a portable media player having video playback and network capabilities, a mobile smart phone having video playback capabilities, a set-top box, or the like.

In general, theGUI10 includes avideo playback area12 and ascrubber bar14. Thescrubber bar14 operates to indicate a playback position of the associated user. In addition, according to one embodiment of the present invention, thescrubber bar14 includes

user identifiers

16,18, and20 indicating playback positions of other users that are also playing the video item. Note that while three

user identifiers

16,18, and20 are illustrated in this example, there may be any number of one or more user identifiers. In this example, the

user identifiers

16,18, and20 are pictures of the corresponding users located on thescrubber bar14 at locations corresponding to the playback positions of the corresponding users. Note that the

user identifiers

16,18, and20 are not limited to pictures of the corresponding users. Other types of user identifiers may be used. Further, additional information may be presented in association with the

user identifiers

16,18, and20. For example, upon selecting theuser identifier16 or hovering over theuser identifier16, additional information such as a status of the corresponding user, contextual information regarding the corresponding user such as the number of users following the corresponding user in playback, personal information regarding the corresponding user, or the like may be presented. While not illustrated, the associated user may select one or more of the

user identifiers

16,18, and20 and initiate a desired action. For example, the associated user may select theuser identifier16 and choose to follow the corresponding user during playback such that playback of the video item for the associated user is substantially synchronized to playback for the user corresponding to theuser identifier16. As another example, the associated user may select theuser identifier16 and initiate a chat session with the corresponding user.

FIG. 3 illustrates anotherexemplary GUI22 for presenting, to a user playing a video item, playback information identifying playback positions of other users also playing the video item at that time according to another embodiment of the present invention. TheGUI22 includes avideo playback window24 and aplayback information window26. In one embodiment, thevideo playback window24 may be provided by a media player software application such as, for example, the Apple® iTunes® media player, Windows® Media Player, the QuickTime® media player, or the like; and theplayback information window26 may be provided by a plug-in to the media player software application. However, the present invention is not limited thereto. Thevideo playback window24 and theplayback information window26 may be provided by a single software application. Further, while theGUI22 of this example is one that would typically be provided by one or more software applications running on a personal computer, the present invention is not limited thereto. A similar interface may be provided by a web browser if the user is playing the video item via the web browser. Still further, a similar interface may be provided on other types of devices such as, for example, a portable media player having video playback and network capabilities, a mobile smart phone having video playback capabilities, a set-top box, or the like.

In general, thevideo playback window24 provides avideo playback area28, ascrubber bar30, and playback controls32. Theplayback information window26 includes, in this example, a list of playback position ranges34-42. Each of the playback position ranges34-42 are more generally referred to herein as expandable group indicators representative of a general playback position of a group of one or more users. In this example, the playback position ranges34-42 are used to collapse multiple users, or playback positions for multiple users, into a single indictor representative of a general playback position for those users. The general playback position may be, as in this example, a playback location range or playback time period. However, the present invention is not limited thereto. The indicator for each of the playback position ranges34-42 may be expanded to view a listing of each user having a playback position within the corresponding playback position range, the specific playback position of each of the users having a playback position within the corresponding playback position range, or both. In this example, theplayback position range38 has been expanded. As a result, alist44 is presented including a name or username of each of the users also playing the video item having playback positions within the range of 00:10:01 to 00:15:00 and the specific playback position of each of those users. In this example, thelist44 includes the users Kunal, Al, and Ravi and their corresponding playback position.

In this example, theplayback information window26 also includes a “follow”button46, a “chat”button48, and a “follow me”button50. In this example, the associated user has selected the user Kunal and may then choose to “follow” Kunal in playback of the video item and, optionally, any number of additional video items subsequently played by Kunal by selecting the “follow”button46, may choose to initiate a chat session with Kunal by selecting the “chat”button48, or may choose to force Kunal to follow him or request that Kunal follow him during playback of the video item by selecting the “follow me”button50. Note that, for the “chat”button48 and the “follow me”button50, the associated user may select one or more users with which to initiate the action. Also note that there may be separate buttons enabling the user to follow Kunal in playback of the video item and enabling the user to follow Kunal in playback of any video item played by Kunal.

It should be noted that the

exemplary GUIs

10 and22 ofFIGS. 2 and 3 are exemplary and not intended to limit the scope of the present invention. In general, information identifying the playback positions of other users may be presented in any desired manner. As another example, referring toFIG. 2, rather than having the

user indicators

16,18, and20, similar expandable group indicators may be used. More specifically, the users for which playback information is to be presented may be divided into multiple groups based on their playback positions. For each group, a corresponding expandable group indicator may be presented on thescrubber bar14 as a position corresponding to a general playback position for the group. The general playback position for a group may be an average of the playback positions of the users in the group, a medium playback position for the users in the group, or the like. The associated user may then click on or otherwise select a desired expandable group indicator. In response, a list of users in the group, the playback positions of the users in the group, or both may be presented to the associated user.

FIG. 4 illustrates asystem52 for presenting, to a user playing a video item, information identifying playback positions of other users playing the video item according to a first embodiment of the present invention. In general, thesystem52 includes acentral content server54 and a number of user devices56-1 through56-N having associated users58-1 through58-N. Thecentral content server54 and the user devices56-1 through56-N are connected via anetwork60. Thenetwork60 may be any type of Wide Area Network (WAN) or Local Area Network (LAN), or any combination thereof, and may include wired components, wireless components, or both wired and wireless components. In one embodiment, thenetwork60 is the Internet.

Thecentral content server54 may be, for example, an Internet server operating to stream or download video items to the user devices56-1 through56-N. As another example, thecentral content server54 may be a server, such as a head-end, in a Cable Television (CATV) network providing a Video On Demand (VOD) service or the like. Thecentral content server54 includes aserver function62 and aplayback information broker64, each of which may be implemented in software, hardware, or a combination thereof. In an alternative embodiment, theplayback information broker64 may be hosted by a separate server such as, for example, a server operated by a third party. As another alternative, theplayback information broker64 may be hosted by a mediating server which can be any node between thecentral content server54 and the user devices56-1 through56-N. Theserver function62 generally operates to provide streaming or downloading ofvideo items66 to the user devices56-1 through56-N. Theplayback information broker64 generally operates to maintain, for eachvideo item66, playback information identifying users from the users58-1 through58-N that are playing thevideo item66 at that time as well as the playback positions of those users. In addition, as discussed below, when, for example, avideo item66 is played at the user device56-1, theplayback information broker64 provides information identifying the playback positions of other users from the users58-2 through58-N that are playing thevideo item66 at that time.

Each of the user devices56-1 through56-N may be, for example, a personal computer, a portable media player having video playback and network capabilities, a mobile smart phone having video playback capabilities, a set-top box, a gaming console having video playback capabilities, or the like. The user device56-1 includes a media playback function68-1 and a playback information client70-1, each of which may be implemented in software, hardware, or a combination thereof. Further, while the media playback function68-1 and the playback information client70-1 are illustrated separately, the media playback function68-1 and the playback information client70-1 may be implemented in a single software and/or hardware application or implemented separately. For example, in one embodiment, the media playback function68-1 and the playback information client70-1 may be implemented in a single media player software application. As another example, the media playback function68-1 may be implemented as, or as part of, a media player software application, and the playback information client70-1 may be implemented as a plug-in to that software application. As a final example, in an embodiment where thecentral content server54 streams thevideo items66 to the user devices56-1 through56-N, the media playback function68-1 and the playback information client70-1 may be implemented within a web browser, as plug-ins to a web browser, or the like.

The media playback function68-1 generally operates to provide playback of video items obtained from thecentral content server54. As discussed above, the video items may be downloaded from thecentral content server54 to the user device56-1 or streamed from thecentral content server54 to the user device56-1. Note thatvideo items66 downloaded from thecentral content server54 may be stored at the user device56-1 and subsequently accessed for playback. When one of thevideo items66 obtained from thecentral content server54 is selected for playback, the playback information client70-1 generally operates to obtain playback information from theplayback information broker64 of thecentral content server54. The playback information includes information identifying playback positions of one or more users from the users58-2 through58-N that are playing thevideo item66 at that time and, optionally, identifying the one or more users from the users58-2 through58-N that are playing thevideo item66. During playback of thevideo item66 at the user device56-1, the playback information client70-1 then presents, or causes to be presented, the information identifying the playback positions of the other users from the users58-2 through58-N that are also playing thevideo item66.

Likewise, the user devices56-2 through56-N include media playback functions68-2 through68-N and playback information clients70-2 through70-N, respectively. The operation of the media playback functions68-2 through68-N and the playback information clients70-2 through70-N are the same as that discussed above with respect to the media play back function68-1 and the playback information client70-1, respectively. As such, the details are not repeated.

FIG. 5 illustrates the operation of thesystem52 ofFIG. 4 according to one embodiment of the present invention. First, in this example, the user device56-1 requests avideo item66 from the central content server54 (step200). Next, thevideo item66 is returned from thecentral content server54 to the user device56-1 (step202). Thevideo66 may be streamed to the user device56-1 or downloaded to the user device56-1. Then, playback of thevideo item66 by the media playback function68-1 begins (step204). In the case of streaming thevideo item66 to the user device56-1, playback may begin automatically after a desired amount of thevideo item66 has been buffered. In the case of downloading thevideo item66, playback may begin upon initiation of playback by the user58-1. In this embodiment, user device56-1, and more specifically the playback information client70-1, notifies theplayback information broker64 of the start of playback of thevideo item66 and, optionally, a starting playback position (step206). However, there may be embodiments where thevideo item66 is streamed to the user device56-1 in such a manner that notification of the start of playback is not needed.

In this embodiment, the playback information client70-1, either automatically or upon receiving a request from the user58-1, sends a request to theplayback information broker64 of thecentral content server54 for playback information for other users from the users58-2 through58-N that are also playing thevideo item66 at that time (step208). In response, theplayback information broker64 of thecentral content server54 identifies other users from the users58-2 through58-N that are also playing thevideo item66 and sends playback information for those other users to the user device56-1 (step210). Alternatively, theplayback information broker64 may automatically push the playback information to the user device56-1. For example, theplayback information broker64 may automatically push the playback information to the user device56-1 in response to receiving notification of the start of playback of the video item or, if thevideo item66 is streamed to the user device56-1, upon receiving a request for the stream of thevideo item66 from the user device56-1.

Again, the playback information includes information identifying the playback positions of the other users playing thevideo item66. For each of the other users, the information identifying the playback position of that user may be, for example, an amount of time from the beginning of thevideo item66 defining the playback position of the user. Alternatively, the playback information may be a general location such as information identifying a segment of the video item being viewed (e.g., chapter) or the like. In addition, the playback information may include information identifying each of the other users playing the video item such as, for example, names, usernames, pictures, or the like.

In one embodiment, the playback information provided to the user device56-1 includes playback information for all other users playing thevideo item66 at that time. In another embodiment, the playback information provided to the user device56-1 includes a subset of all of the other users playing thevideo item66 at that time. More specifically, as discussed above, theplayback information broker64 may provide the playback information for a subset of all of the other users playing thevideo item66 identified based on one or more criteria such as, for example, geographic location, geographic distance from the user58-1, demographic information (e.g., age, sex, or the like), a social network of the user58-1, similarity of user profiles and/or preferences of the other users to a user profile and/or user preferences of the user58-1, or the like. The criteria to be used for filtering may be predefined by theplayback information broker64, predefined by the user58-1, or defined by the user58-1 at the time of making the request. If defined by the user58-1, the criteria may be provided, for example, within the request.

For example, theplayback information broker64 may first identify a list of other users from the users58-2 through58-N currently playing thevideo item66 and filter the list based on geographic location to remove users that are not located within the same geographic location as the user58-1. The geographic location may be any geographic region such as, but not limited to, a country, a region of a country, a state, a city, a town, an area defined by a telephone area code, an area defined by a zip code, an area defined by geographic designations such as latitude and longitude, or the like. The geographic locations of the users58-1 through58-N may be determined using any known location-determination scheme. For instance, the location of the users58-1 through58-N may be determined using Global Positioning System (GPS) receivers within or otherwise associated with the user devices56-1 through56-N; determined based on Internet Protocol (IP) addresses of the user devices56-1 through56-N; obtained by theplayback information broker64 from information provided by the users58-1 through58-N such as, for example, mailing addresses or phone numbers; or the like. As another example, the list of other users from the users58-2 through58-N currently playing thevideo item66 may be filtered to remove users that are not within a defined geographic, or physical, distance from the user58-1.

As another example, the list of other users from the users58-2 through58-N currently playing thevideo item66 may be filtered to remove users that do not have demographics matching those of the user58-1, demographics identified by the user58-1 as preferred demographics, demographics within a defined range of the demographics of the user58-1, or the like. For example, if the user58-1 has indicated he is 29 years old, theplayback information broker64 may remove users from the list whose ages are not within a defined age range such as, for example, 25-35 years old. As another example, the user58-1 may indicate that he wishes to see the playback positions of other users that are within the age range of 25-35 years old, female, and not married. As such, theplayback information broker64 may filter the list of other users playing thevideo item66 based on these criteria in order to provide the filtered list of users for which to provide playback information to the user device56-1.

As a final example, the list of all other users from the users58-2 through58-N currently playing thevideo item66 may be filtered to remove users that are not within a social network of the user58-1, within a defined logical distance from the user58-1 in a social network of the user58-1, on a contact list such as an email contact list or buddy list of the user58-1, or the like. In one embodiment, information defining the social network of the user58-1 may be hosted by thecentral content server54 or obtained from a social networking service such as, for example, a social networking website such as MySpace®, LinkedIN®, or the like. For example, each of the users58-1 through58-N may be required to register with thecentral content server54 and provide a username or other user ID used in a social network hosted by a social networking service. Theplayback information broker64 may then query the social networking service using the username or other user ID of the user58-1 to obtain the usernames or other user IDs defining the social network of the user58-1. Theplayback information broker64 may then correlate the usernames or user IDs of the users in the social network of the user58-1 to those provided by the other users from the users58-2 through58-N that are playing thevideo item66 during registration to identify other users that are playing thevideo item66 and are also in the social network of the user58-1. Similarly, theplayback information broker64 may identify those other users that are playing thevideo item66 and are also within a desired degree of separation from the user58-1 in the social network of the user58-1. In a similar manner, a contact list of the user58-1 may be hosted by thecentral content server54, obtained from the user device56-1, or obtained from a remote source such as, for example, a web-based email service and used to filter the list of other users currently viewing thevideo item66.

Again, the manner in which the playback information is presented to the user58-1 may vary. For example, the playback information may be presented as user indictors on a scrubber bar in a manner similar to that shown inFIG. 2. As another example, the playback information may be presented as a list of playback positions for the other users playing thevideo item66 or a list having expandable/collapsible playback time ranges similar to that shown inFIG. 3. As another example, as discussed above, the playback information may be presented in a collapsible form using expandable group indicators on a scrubber bar in a manner similar to that shown inFIG. 2. As discussed above, the playback information presented to the user58-1 may be automatically updated in a manner that assumes continued playback of thevideo item66 by the other users. The playback information may be further updated based on updates received from theplayback information broker64 in response to playback control events during playback of thevideo item66 by the other users.

In this example, the user device56-1, and more specifically the media playback function68-1, receives user input from the user58-1 changing the playback position of the user58-1 (step214). For example, the user58-1 may instruct the media playback function68-1 to fast-forward, rewind, or the like. In response, playback is controlled, and the playback information client70-1 sends an update to the playback position of the user58-1 to theplayback information broker64 of the central content server54 (step216). Using the starting playback position of the user58-1, the updates to the playback position of the user58-1 in response to playback control events, and an internal clock or timer, theplayback information broker64 is enabled to maintain the current playback position of the user58-1. In a similar manner, the playback information client70-1 is enabled to maintain, or update, the playback positions of the other users. In an alternative embodiment, the user device58-1 may send periodic updates to theplayback information broker64 for the playback position of the user58-1 such that theplayback information broker64 is enabled to maintain the current playback position of the user58-1.

In this example, at some point in time, theplayback information broker64 of thecentral content server54 receives a playback position update from one of the other users currently playing the video item66 (step218). In response, theplayback information broker64 of thecentral content server54 sends an update to the playback information to the user device56-1 (step220), and the playback information client70-1 updates the information presented to the user58-1 at the user device56-1 (step222).

Also in this example, at some point in time, the playback information client70-1 receives user input from the user58-1 identifying a desired action to take with respect to one or more of the other users currently playing the video item66 (step224). In response, the playback information client70-1 effects, or causes, the desired action (step226). For example, as discussed above, the user58-1 may select one of the other users and choose to “follow” the selected user in playback of thevideo item66. The playback information client70-1 may then control the media playback function68-1 based on the playback information, and any updates thereto, provided to the user device56-1 for the selected user such that playback of thevideo item66 to the user58-1 is substantially synchronized to playback of thevideo item66 to the selected user.

As another example, as discussed above, the user58-1 may select one or more of the other users and choose to have them “follow” him in playback of thevideo item66. In response, in an exemplary embodiment, the playback information client70-1 may notify thecentral content server54. Thecentral content server54 may then request approval from the selected users. If the selected users approve, then playback of thevideo item66 by the corresponding user devices of the selected users is controlled based on playback information provided to those user devices such that playback of thevideo item66 at those user devices is substantially synchronized with playback at the user device56-1. Alternatively, thecentral content server54 may force the other users to follow the user58-1 in playback of thevideo item66 without their approval.

As a final example, the user58-1 may select one or more of the other users and choose to initiate a chat session with those users. The chat session may be initiated by a third party chat application. Any information needed to initiate the chat session, such as usernames or user IDs, may be provided to thecentral content server54 during registration and obtained from thecentral content server54 as needed. Alternatively, such information may be provided within or in association with the playback information.

It should be noted that while the discussion above focuses on the playback of video items streamed or downloaded from thecentral content server54, the present invention is not limited thereto. In addition or alternatively, the present invention may be utilized with respect to playback of video items obtained from local sources such as, for example, Digital Video Disc (DVD) players incorporated into or connected to the user devices56-1 through56-N. Thus, for example, the user device56-1 may be providing playback of a video item from an associated DVD player, the user device56-2 may be providing playback of a previously downloaded copy of the video item obtained from thecentral content server54 or some other content source, and the user device56-3 may be providing playback of a stream of the video item from thecentral content server54. Then, with respect to the user58-1, playback information for the other two users58-2 and58-3 also playing the video item is obtained from theplayback information broker64 and presented to the user58-1. Likewise, with respect to the user58-2, playback information for the other two users58-1 and58-3 playing the video item is obtained from theplayback information broker64 and presented to the user58-2. Finally, with respect to the user58-3, playback information for the other two users58-1 and58-2 playing the video item is obtained from theplayback information broker64 and presented to the user58-3.
